Optus Resin offers a range of solvent free epoxy primers and single pack polyurethane primers, they are used to seal and prepare surfaces prior to the application of epoxy or polyurethane coatings, self-smoothing systems or screed materials. Our epoxy primers come as 2 pack and our polyurethane primes come as single packs. They absorb into the existing substrate, curing stronger than concrete itself and seal effectively. By using an epoxy primer you improve the coverage of your coatings and provided a sealed barrier layer between the substrate and the wearing layer. Our epoxy primers adhere extremely well to epoxy based coatings and systems as well as polyurethane resin systems. Our polyurethane primers provide a fast curing option for polyurethane systems in exterior situations.
